At the foot of the Altiplano in northern Argentina lies the wide and sandstone covered valley of Brealito at 2500m of altitude. The place is as calm and beautiful as it can be and there are some thousands of boulders to open (and to brush).

Murciélago is an 8m high athletic, powerful sequence of 15 hard moves (before some meters of slap) on roundly shaped holds with difficult hooks and a long way to the mantle. (I got to the edge only at the horn. Otherwise it is somewhat easier.) In three sessions and some perfect evening conditions I sent it – bats (murciélago) crossing behind me -, after three weeks of travelling towards the Altiplano through the Argentinian Andes in the end of April.
